Part Number: TIDA-010080 Hi Experts,
I am interested in using just the LLC stage and the output SR stage for a 600W DC-DC design. How would I calculate the input capacitance if I do not use a PFC stage?

How to calculate L5 inductor values,we require current ripple about 2% of Load current 20A.
advise me how to calculate L value here please
thanks in advance
Part Number: TIDA-010081 Other Parts Discussed in Thread: TIDA-010080 good morning,
In 1KW Ref design, output side Resistor (DNP as shown) is required or not.
for us output voltage shoots to 80V.our set point is 61V only.we have not populated this Resistor…
Part Number: UCC24624 Rds constrain is there for this active synchronous rectification.
for us 1kw LLC converter,output side synchronous rectification mosfet Rds=16mohm.
while testing bottom side mosfet blows off.we just followed
Thank you for the query.
I would recommend the following controller choices and reference design:

Thanks for your answer, Harish.
We will double check the inductor value, thanks again for your support! do you think this could be the reason behind the damaged PFC ICs?
